[Lee, Daniel]

We tested the IDP-3 that is connected to the Vacuum Oven. It turns on with a somewhat annoying sound, but this goes away quickly. The oven reaches its final pressure of 15 Torr in around 10 minutes.

We turned the pump off at 4 PM. At 11:15 AM the next day, the pressure was 30 Torr. This is a leak rate of 0.02 mbar L/s. 

With that leak rate and a pumping speed of 1 L/s, I would expect a final pressure of 0.02 mbar = 0.015 Torr.

The quoted base pressure of the IDP 3 is 0.25 Torr.

This could be explained by an improperly calibrated dial on the pump, and the vacuum is closer to 1 Torr.
